To all 'tvho'm. concern: i p

Be it known that I, ARTHUR A. KRAEUTER,

a citizen of'the' United States, residing at.

- fit, an the objects of the invention are to secure such a tool of simple and convenient construction, which can be readily sharpened upon becoming dull, and to obtain j other advantagesand results as may be brought out in' the following description.

Referring to the accompanying drawings,

in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 1s a side; elevation of'ia scrapingtool of my improyed construction;

Fig. 2 is an underneath view of the tool, and

. Fig. 3 is a cross section taken on line 3-3 of Fig. 1 and looking in the direction indicated by the arrow.

In said drawings, portion ofa scraplng tool, and 11 '-a portion of a shankformed integral with said body portion. This shank 11 provides in any suitable and ordinary manner for the attachment of a handle of any common and well-known construction to be grasped by the workman in usin the tool; It is thought unnecessa to i lustrate this handle in detail. The sai bodyfportion 10 of my.

improved scraping tool is 1n plan'somewhat tapering and narrows to a point' at its end farthest from its shank 11. In edge view, as shown in Fig. 1, said body portion 10 curves gently u wardtoward its said point 1'2 justreferre to. The top of the body portion 10 is preferably curved: or. rounded transversely, as at 13 in 3.

In the bottom of the b' y-portion 10 is a recess 14 extending longitudinally of said portion 10 body portion nearly to its point 12, and thus leaving. at the opposite edges of the body portionlO downwardly depending ribs 15, 16 which follow the shape of the bod hese ribs' 15',' 16 are of substantially uni-. form thickness or'cross sectional area, and preferably this is such as best adapts them 15 and 16 are 10 indicates the bodyand meet at the point 12 thereo i to the scraping of metal. The outer edge walls of the body portionlO, which it will be seen'are the outer sides of the ribs 15, 16, are preferably flattened or ground off, as at 17. When therefore the faces ,of the. ribs ound off transversely .of the tool, sharp cutting edges 18 are formed at the outer corners of said ribs 15, 16. Furthermore, these cutting edges can be renewed or sharpened atany time desired by simply setting the tool flat upon the grmdstone. Great ease ofjsharpenin is thus obtained, and the tool may be use vand sharpened a great many timesbefore the ribs 15 and 16 become-worn down too much. Grinding or sharpenin is also, made very simple.

'It will e understood that the workman takes the tool by its handle or shank, and setting ther'rbs 15,16 upon the workto be scraped, he hears uponthe to of the tool and gives it an obliquely sidewlse movement.

The two narrow cutting ribs :15 and 16 adapt the tool to be used efliciently or similarly curved surfaces ferent radii. I 1

Havin thus described the invention, whatIcaimis:

1. The herein. described scraping 1 tool, comprising a body portion having at its under surface separated depending ribs whose ground faces provide sharp mam] edges at u on bearings 01' widely difthe outer sides'of the scraper, an a-shank for said body portion.

2. The herein described scraping tool, comprising an integral shank, and a body ortion, said body portion tapering away rom said shank and having at itsgunder. surface marginal ribs which converge toward the point of the scraper and are sharpened at their faces. v

3. The herein described scraper, comprising a body portion tapering to a point at its forward endand being curved upwardly, said body portion having a longitudinal median groove or recess in its under side providing cutting ribs at o posite edges of the tool, said cutting ribs eing ground at their faces and at the outer sides of the tool, and a shank for said bodyportion'.
